U.S Heart Patients Vs Canadian Heart Patients


Elderly patients with heart failure who are hospitalized in the United States have lower death rates at 30 days than patients hospitalized in Canada for the same illness, but one-year death rates are similar in the U.S. and Canada, as per a studyin the November 28 issue of the Archives of Internal Medicine, one of the JAMA/Archives journals.

The United States and Canada have different methods of financing and providing health care. The U.S. market-oriented system with limited governmental control is in sharp contrast to Canada's single-payer system, which covers most clinician and hospital services and prescription medications. Canadian budgetary restraints have resulted in limited access to specialized care, such as invasive cardiac procedures and clinician specialists, according to background information in the article. Health care expenditure per person is significantly higher in the U.S. compared with Canada, but whether there are differences in quality of care of a number of conditions is unknown.

Dennis T. Ko, M.D., of the University of Toronto, Ontario, and his colleagues compared processes of care and 30-day and one-year risk-standardized mortality rates among 28,521 U.S. Medicare beneficiaries and 8,180 similarly aged patients in Ontario, Canada, who were hospitalized with heart failure from 1998 to 2001. Heart failure-a condition in which the ventricles, or lower chambers of the heart, are not able to pump blood effectively-is the most common cause of hospitalization for individuals aged 65 and older in both countries.

"More U.S. patients underwent left ventricular ejection fraction assessment [a test to evaluate the pumping action of the lower chambers of the heart] during hospitalization compared with Canadian patients (61.2 percent vs. 41.7 percent)," the authors write.

The authors also looked at the use of medications usually prescribed for heart patients. "At discharge, patients in the United States were prescribed beta-blockers more frequently (28.7 percent vs. 25.4 percent), but angiotensin-converting enzyme inhibitors less frequently (54.3 percent vs. 63.4 percent)," they report.

The death rate at 30 days was significantly lower for U.S. patients-8.9 percent compared with 10.7 percent for Canadian patients. But at one year, the death rates for patients in both countries were similar-32.2 percent vs. 32.3 percent.

"In conclusion, we found that HF patients hospitalized in the United States had significantly better short-term mortality but equivalent long-term mortality compared with a sample of HF patients hospitalized in Canada," the authors conclude. "Further studies are needed to explore the reasons underlying this difference in outcomes and to gain additional insights to improve the care and outcomes of HF patients in both countries."
